APRON-GANVAS.

Specification of Letters Patent.

Application filed December 6, 1916. Serial No. 135,347.

To all whom it may concern:

Be it known that I, AMMIEL F. DECKER, a citizen of the United States of America, residing at Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Apron-Canvas, of which the following is a specification.

This invention relates to improvements in the manufacture of apron-canvas, for use in the construction of endless aprons or belts for laundry and other machines.

In constructing aprons of the general character specified, it is customary to utilize a single long strip or section of heavy canvas, or, in some cases, two or more shorter sections of uniform width and, in many instances, of uniform length as well; the ends of this canvas section are fastened together to form the apron, or, if more than one section is used, the sections are connected end to end. It frequently happens, however, that an apron constructed in this manner, does not run true, but has a tendency to shift or slide to one side or the other during its travel, due to improper joinder of the section or sections, or to irregularities in the manufacture thereof, with the result that the operation of the machine is impeded and the apron itself, as well as the articles supported upon it, is liable to become injured.

It is the purpose of the present invention to overcome this defect by incorporating in the canvas section or sections, preferably during the process of manufacture, a plurality of indicating or guiding lines, which are disposed longitudinally thereof and at precisely the same distances from the marginal edges. These lines are of a color which presents a marked contrast to that of the canvas, and for that reason, are readily perceptible. Hence, it follows that since said lines are perfectly straight, and are positioned with absolute accuracy, any irregularity at once becomes apparent, this with reference both to the canvas itself and to its manner of joinder. Consequently, defective sections can readily be detached, and replaced by perfect ones, and, similarly, errors in joinder can easily be corrected before the completion of the apron, so that waste and loss of time are avoided, as well as the construction of imperfect aprons. And for the same reason, the true running of the finished apron is insured, since the aforesaid colored lines will enable the initial correct positioning of the apron upon its rollers, and its subsequent adjustment if for any reason it becomes displaced.

The accompanying drawing illustrates a practical embodiment of the invention which, for all present purposes, may be considered as preferred, although it is to be understood that no limitation to the precise structure itself is intended.

In said drawing:

Figure l is a broken plan view of an apron constructed in accordance with the invention.

Fig. 2 is a transverse section of the strip.

Fig. 8 is a plan view, on a reduced scale, of an apron made up of a plurality of the sections.

Referring more particularly to said drawing, it will be observed that the apron may be constructed either of a single, long section 1, (Fig. l), or of a plurality of separate sections 2, arranged end to end, the ends of the section or sections being fastened together by stitching 3, or in any other suitable manner, the number of sections employed depending, in each instance, upon the length of the particular apron. These sections 1 or 2, which may be of any desired width, ranging as high as 120 inches, are constructed of heavy canvas, as previously stated.

Durin manufacture, or, in any event, before joining together the ends of the section or sections to form the apron, the section is provided with a plurality of the indicating lines above referred to, said lines being of a color which is in marked contrast to the whitish surface of the canvas; for instance, a bright blue, though some other color might be used with equal success. In the construction illustrated, four such lines are shown, two lines 4 being located at a slight distance from the marginal edges 6 of the canvas strip, and the other two lines 5 being spaced intermediate thereof, the spaces between adjacent lines being substantially equal. In the construction of any particular apron, however, the canvas will have exactly the same width throughout, so that in manufacturing the section or sections, the distance between the various lines will be constant and must be determined with the utmost accuracy. That is to say, the relative distances between the marginal edges 6 of the apron and the four colored lines 4, 4:, 5

and 5, must be exactly the same throughout the entire length of the canvas, in order to enable the ends of the lines to meet each other and aline with absolute accuracy, and, in the case of a multi-part apron, to enable the lines of each succeeding section to aline with those of the preceding section and thereby form absolutely straight, continuous lines.

In actual manufacture, it is preferred to utilize colored threads or strands for the production of the indicating or guiding lines, these threads or strands being interwoven into the canvas.

I claim as my invention 1. An apron-section, comprising a strip of flexible material provided upon its surface with a plurality of visible indicating lines disposed longitudinally and at predetermined distances from one another and from the marginal edges of the section, so that when the ends of the section are brought together, or when a number of identical sections are placed end to end, to form the apron, the said lines will exactly register with, and will constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correct positioning and joinder of the section ends and correct running of the apron.

2. An apron-section, comprising a strip of flexible material provided upon its surface With a plurality of visible indicating lines of a color Which presents a marked contrast to the color of the material itself, said lines being disposed longitudinally and at predetermined distances from one another and from the marginal edges of the section, so that when the ends of the section are brought together, or when a number of identical sections are placed end to end, to form the apron, the said lines will exactly register with, and will constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correct positioning and joinder of the section ends and correct running of the apron.

3. An apron-section, comprising a strip of textile material provided upon its surface with a plurality of visible indicating lines of a color which presents a marked contrast to the color of the material itself, said lines being disposed longitudinally and at predetermined distances from one another and from the marginal edges of the section, so that when the ends of the section are brought together, or when a number of identical sections are placed end to end, to form the apron, the said lines will exactly register with, and will constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correctpositioning and joinder of the section ends and correct running of the apron.

4. An apron-section, comprising a strip of textile material having a plurality of strands, of a color presenting a marked contrast to the color of the material itself, said strands being interwoven thereinto to form visible indicating lines disposed longitudinally and at predetermined distances from one another and from the marginal edges of the section, so that when the ends of the section are brought together, or when a number of identical sections are placed end to end, to form the apron, the said lines will exactly register with, and will constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correct positioning and joinder of the section ends and correct running of the apron.

5. An apron-section, comprising a strip of flexible material provided upon its surface with a pair of visible, longitudinal indicating lines located in predetermined proximity to its marginal edges, and with a pair of additional, spaced indicating lines located intermediate of, and parallel with the first-named lines, the spaces between adjacent lines being substantially equal, so that when the ends of the section are brought together, or when a number of identical sectionsare placed end to end, to form the apron, the said lines will exactly register with, and will constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correct positioning and joinder of the section ends and correct running of the apron.

6. An apron-section, comprising a strip of flexible material provided upon its surface with a pair of visible, longitudinal indicating lines located in predetermined proximity to'its marginal edges, and with a pair of additional, spaced indicating lines located intermediate of, and parallel with the firstnamed lines, the spaces between adjacent lines being substantially equal, and all of said lines being of a color Which presents a marked contrast to the color of the material itself, so that when the ends of the section are brought together, or when a number of identical sections are placed end to end, to form the apron, the said lines will exactly register with, and will. constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correct positioning and joinder of the section ends and correct running of the apron.

7 An apron-section, comprising a strip of textile material having a plurality of strands, of a color presenting a marked con-.

trast to the color of the material itself, said strands being interwoven thereinto to form visible indicating lines, two of sa d lines being located in predetermined proximity to, and parallel with, the marginal edges of the section, and the other two lines being located intermediate of, and parallel with the first-named lines, the spaces between adjacent lines being substantially equal, so that when the ends of the section are brought together, or when a number of identical sections are placed end to end, to form the apron, the said lines will exactly register with, and will constitute absolutely accurate continuations of, one another, the continuous lines forming guides to insure correct positioning and oinder of the sec tion ends and correct running of the apron.

8. An apron-section comprising a strip of textile material having a pair of strands, of a color presenting a marked contrast to the color of the material itself, said strands being interwoven thereinto in predetermined proximity to, and parallel with, its marginal Witnesses MAE A.
